Again, climate was the reason, but this time suspicion fell on a human-induced change.
In 1988, Dr Hansen testified before the US Congress, arguing that human induced climate change had begun.
CO2 is the greenhouse gas of greatest concern to policy makers looking to stem human-induced climate change.
That will help those who seek to understand the carbon cycle and with it, the consequences of greenhouse-gas-induced climate change.
By contrast, human-induced climate change is thought to have raised global temperatures just 0.6 degrees Celsius during the past 150 years.
According to Prof Roger Pielke Jnr, from the University of Colorado, there are big dangers in claiming that one event, be it US weather records or wildfires in Australia, are clear evidence of human-induced climate change.
No climate agreement will succeed without support from those countries that have so far contributed little to human-induced climate change, have low per-capita emissions, and stand to face the biggest challenges in adapting to the coming changes.
The recent heat wave that has fried much of the country, ruined crops and led to heat-related deaths has again raised the question of whether this and other extreme weather events can be attributed to human-induced climate change.
In addition to having to make up for often very substantial, but contingent equity, pension and other values left behind, the board wants, by definition, someone who is successful where he or she is and more often than not needs to be induced to change course.
Was this fluctuation real, or was it merely a glitch in the equipment used to measure the decay, induced by the change of seasons, with the accompanying changes in temperature and humidity?
FORBES: Radioactive Decay Rates May Not Be Constant After All
But according to this research, wheat will face a difficult future in the developing world, where higher prices for cotton, maize and soybeans have pushed wheat to marginal land, making it more vulnerable to stresses induced by climate change.
These will be spread like wild-fires by frequent climate change-induced weather events of catastrophic proportions.

Science plays an important role in our response to global issues such as climate change, the hydrological cycle, biodiversity loss, natural hazards and human-induced disasters, population growth, land-use change, migration and urbanisation.

In the wake of the announcement, Planned Parenthood announced it would change the way it administers drug-induced abortions.
Prof Lee added that human-induced pressures, such as hunting, along with projected climate change and habitat loss, have the potential to change the dynamics of elephant populations and, jeopardise the long-term future of the species.
Yes, they get into some gross and drug-induced situations but they also deal realistically with issue of growth and change.
